Bell

The OGLAS bell is the noise-maker. It sits in the house, the office, the shed — wherever you want to hear about things — and turns sensor activity into sound.

What it does

There are three ways the bell rings:

• Pattern match on incoming sensor activity — by default, when the gate opens, the bell triggers a single buzz. Rate-limited so a flaky link can’t replay the same event into a buzz-storm.
• Direct ring command — a single, immediate buzz with no cooldown. Use this for manual or scripted pings from the hub.
• Alarm mode — a repeating tone for a configurable window (default 60 s). Re-issuing the command extends the window.

Plus remote mute/unmute, and an on-board mute button that toggles silence with a fast-flashing LED to show the bell is alive but quiet.

Group ringing

Bells can be grouped so a single command rings every bell on site at once — useful if you have one in the house and one in the shed, or one in the office and one on the floor.

Pairs well with

• Gate — the most common trigger: gate opens, bell rings.
• Vehicle Track — chirp when someone arrives or leaves; alarm when a generator stops unexpectedly.
• Electric Fence — bell rings the instant the fence stops pulsing.
• Water Trough — out-of-water alert rings the homestead bell.
• Tank level — bell on tank-low to walk down and check.
• Smart Switch — failure or “load not running” alerts ring through the bell.
